Disclosed is a vehicle charging device that can perform communication even if the vehicle charging device and a charging instruction device are connected to power line pairs having different phases in a multiple-wire power line. The vehicle charging device (6) is provided with: a power line communication unit (61) that performs communication over a multiple-wire power line or a power line (7) for vehicles; a power line connection unit (63) that connects a pair of power lines within the multiple-wire power line to the power line (7) for vehicles; and a control unit (62) that controls the connection or the disconnection of the power line connection unit (63). The power line communication unit (61) selects a signal from a pair of power lines within the multiple-wire power line and communicates with the charging instruction device, and performs communication with the vehicle over the power line (7) for vehicles. |
